Inching through the windows binaries which came with the card this seems to be oem version of one of the Ositech cards maybe Seven of diamonds, not entirely sure.
--Probably why smc91c92_cs driver makes some headway before bailing out.

currently hacking the driver round a bit at the moment to see if i can force it into recognising the card. More anon...

oh... and do you have the hw addresses of any of the Ositech cards currently out, maybe one matches the ositech address on this card 00 c0 e3 0f 70 6e?
